Located in Ikegami, Ota Ward, Tokyo, Kagayama Pediatric Clinic specializes in general pediatric care and the treatment of allergic conditions including atopic dermatitis, asthma, and food allergies. Since April 2023, the clinic has implemented a two-doctor system to accommodate patients' doctor preferences. Allergy clinics are held on Wednesday mornings and Tuesday and Wednesday afternoons, while preventive vaccinations and infant health checkups are conducted on the first Sunday of each month. The clinic also offers sublingual immunotherapy for pollen (cedar) and dust mite allergies. To prevent in-hospital infections, the clinic arranges private waiting areas for patients with symptoms such as fever, vomiting, diarrhea, or rash. All visitors undergo temperature checks, and masks are required for children aged 3 and above, demonstrating a strong commitment to hygiene management. The clinic offers online queue reservations for returning patients, with real-time status updates. Additionally, the clinic features English language support, parking, and barrier-free facilities.
